commonfactor model failing to converge

[Emily Morbey]

Hi, I keep getting this error when I try to use the comon factor model with DWLS:  The common factor initially failed to converge. A lower bound of 0 on residual variances has been added to try and troubleshoot this.

I didn't used to get this error, and am using the same data as previously when the common factor model had worked with DWLS. I have tried taking variables out in different orders but nothing seems to be working. The correlation between my traits is >0.5 in most cases. I wondered if you had any suggestions I could try?
